Task & challenge
Year 2003, we started working to date with our DEMMEL AG, headquarter in Scheidegg on this product series.
The Siemens Siprotec series digital protection relays and control calls for much comprehensive membrane keyboard design with numerous layers, EMF shielding & components mounting & assembly.
Upholding its stringent electrical specifications requirement, we pledge ourselves that they remain top notch human machine interface membrane model in its field modular application.
Development & Production:
2003 to date
Applied skill:
Screen print, high temperature embossing, semi-auto lamination, die-pressing, burn-in, open/ short circuit & insulation electrical tests
Iconic client branding overlay combining visual elements that represent the client's brand with the process of screen printing.
Distinct top and bottom printed circuit layer with multiple layers of conductive traces separated by insulating layers.
Printed shielding protection creates layers that shield electronic components from electromagnetic interference (EMI) or radio frequency interference (RFI). Prevents external signals from affecting the proper operation of sensitive components.
Components assembly: silver epoxy bonding to LEDs , tactile dome to sub-layers.
